# Get Currency by Country

> Retrieve the official currency for a single country by ISO2, ISO3, or numeric ID

Retrieve the currency used by a single country. The path parameter accepts **three forms** for flexibility:

* ISO 3166-1 alpha-2 code (e.g., `US`, `IN`)
* ISO 3166-1 alpha-3 code (e.g., `USA`, `IND`)
* Numeric country ID (e.g., `233` for the United States in our database)

<Note>**Availability:** Supporter plan and above. Returns `403` on lower tiers.</Note>

<Info>Responses are cached server-side for 24 hours. Equivalent identifier forms (e.g., `1` and `001`) resolve to the same cache slot.</Info>
